As it happens, I value deep reading – and so, perhaps, do you. And so, quite obviously, do all the youngish people I see everyday on London transport reading 700-page printed books such as the Game of Thrones series, 50 Shades of Grey or the new Donna Tartt. Stuart Jeffries has written persuasively about the popularity of such doorstops, as well as complex modern TV series. This might be a culture not of attention deficit but of “a wealth of attention focused more readily on the things that warrant it”.
